Well I've been interested in lucid dreaming for a while and have had some results but am I wondering about this feeling I get often before going to sleep. I lay down and close my eyes and sometimes I get this feeling of me or my mind getting rocked back and forth or being flipped or spinning. I dies down and usally doesnt last anymore than a few seconds sometimes but I am just wondering if this has anything to do with sleep or dreaming? Any comments are apperciated.
